Predicting what may occur in this circumstance would be difficult even if we knew what type of birth control pill you take. First, we need to determine if you are pregnant, which would change everything. Either way, you should make an appointment with a gynecologist and let them determine the nuances of your menstrual cycle and verify the etiology of your bleeding. It isn't always hormones.
